## Reflection: Rigor Wax Paper Activity (Day 2 of 2) - Section 2: Find equations of Conic Sections

One of the great things about the project is the amount of instruction that the students did as they worked. The group in this clip is a great example.

In the first part of the clip a student is explaining how the students need to make sure the scale matches the equations.  She has connected the ideas from coordinate geometry to the project.

The second part of the video shows this students again explaining some mathematical procedure. One student says she still doesn't understand how to get rid of the square. this student show the student how to do this on a piece of paper.

Everyone always says that we know a student understands a process when they can teach the process to another student. This part of the video demonstrates the truth of this concept.

Here is another example of students helping each other. Here a student is directing a student on how to write the standard equation of a circle. The student writing says you can now factor and the other the student working with him says "Why do you need to factor?" This is a question I would ask which is amazing to see how students are now questioning each other to think and reason.

It was exciting when a group finished their project and announced that they had used their notes and helped each other learn how to write equations for the conics. This group had several students that had struggled with the beginning of the unit. The leader of this group stated that I could ask any of the students and they could tell me how the equation was found and why. This group was so proud of what they had learned and I am sure will remember this unit for a long time.
